Which of the following statements regarding animation in a slide use is true?

The statement that animations occur On Click by default is accurate because in most presentation software, including applications like Microsoft PowerPoint, the default setting for animations is to trigger on a mouse click. This allows presenters to control the flow of the presentation, introducing elements one at a time. This feature is particularly useful for ensuring that the audience's attention is focused on the current point being discussed before moving on to the next one.

In contrast, the options suggesting that animations play automatically or cannot be reordered are not typically the default behavior of most presentation software. Additionally, it is common practice to add animations at any stage of slide creation, allowing for flexibility in editing presentations.
